​High-Pressure Diaphragm Pump

A high-pressure diaphragm pump is a type of positive displacement pump used to transfer fluids at high pressure with precise flow control. These pumps are especially suitable for corrosive, toxic, abrasive, or sensitive fluids.

🔧 How it Works
• The reciprocating movement of a flexible diaphragm creates suction and discharge.
• The diaphragm separates the fluid from mechanical components, resulting in minimal leakage.

⚙️ Features
• High outlet pressure (from several tens of bar up to over 1000 bar in industrial models)
• Suitable for corrosive and hazardous fluids
• Accurate and adjustable flow rate
• Can run dry (in some models)
• Relatively easy maintenance

🧪 Applications
• Oil, gas, and petrochemical industries
• Chemical injection (dosing)
• Pharmaceutical and food industries
• High-pressure cleaning systems
• Transfer of slurries and viscous fluids

🔍 Types of High-Pressure Diaphragm Pumps
• Hydraulic diaphragm pumps
• Pneumatic (air-operated) diaphragm pumps
• Electric diaphragm pumps
• Diaphragm metering (dosing) pumps

✅ Advantages
• High safety (no contact between fluid and moving parts)
• Suitable for high-pressure applications
• High accuracy in dosing

❌ Disadvantages
• Higher cost compared to standard pumps
• Lower flow rate compared to centrifugal pumps
• Diaphragm may be sensitive to damage under improper conditions
